Cov pob zeb granite thiab cov rooj ua haujlwm yog cov khoom tseem ceeb ntawm cov tshuab ntsuas peb-seem. Cov tshuab no siv rau hauv ntau yam lag luam, suav nrog aerospace, automotive, kev kho mob, thiab kev tsim khoom meej, qhov twg qhov tseeb thiab qhov tseeb yog qhov tseem ceeb tshaj plaws. Kev siv granite ua kom muaj kev ruaj khov thiab kev tswj kev co hauv qab kev txav mus los ceev ceev, uas yog qhov tseem ceeb rau kev xa cov kev ntsuas tseeb thiab txhim khu kev qha.
Granite yog ib yam khoom zoo tagnrho rau lub spindle thiab worktable vim nws cov khoom zoo heev. Granite yog ib hom pob zeb igneous uas tsim los ntawm kev khov ntawm molten magma. Nws yog ib yam khoom siv ntom thiab tawv uas muab kev tiv thaiv zoo rau kev hnav, xeb, thiab deformation. Granite muaj cov coefficient qis ntawm thermal expansion, uas ua rau nws tsis tshua muaj kev cuam tshuam rau thermal deformation nyob rau hauv ntau yam kub. Ntxiv mus, granite muaj qib siab ntawm kev ruaj khov, uas ua kom ntseeg tau tias muaj kev ntsuas sib xws thiab raug.
Kev siv cov pob zeb granite spindles thiab worktables hauv cov tshuab ntsuas peb-seem muaj ntau yam zoo. Ua ntej, granite muab cov qauv ruaj khov thiab nruj uas txo qhov deflection thiab txhim kho qhov tseeb ntawm lub tshuab ntsuas. Granite muaj qhov ceev siab, uas ua kom lub tshuab ruaj khov txawm tias nyob hauv kev txav mus los ceev ceev. Qhov rigidity ntawm granite ua kom ntseeg tau tias muaj me ntsis lossis tsis muaj kev co thaum lub sijhawm ntsuas, uas ua kom cov txiaj ntsig raug.
Qhov thib ob, kev siv cov pob zeb granite spindles thiab worktables ua kom muaj kev ruaj khov thermal. Granite muaj cov coefficient qis ntawm thermal expansion, uas txhais tau tias nws teb qeeb heev rau kev hloov pauv ntawm qhov kub thiab txias. Qhov no txo qhov kev pheej hmoo ntawm thermal distortion thaum lub sijhawm ntsuas. Granite kuj muaj cov thermal conductivity zoo heev, uas ua kom ntseeg tau tias cov cua sov tsim tawm thaum lub sijhawm ntsuas tau dissipated sai, txo qhov thermal expansion thiab distortion.
Qhov thib peb, cov pob zeb granite spindles thiab cov rooj ua haujlwm tiv taus kev hnav thiab xeb. Vim nws qhov nyuaj, granite tiv taus kev hnav thiab tsim kua muag ntawm kev txav mus los ceev ceev, ua kom ntseeg tau tias lub spindle thiab lub rooj ua haujlwm nyob rau hauv zoo rau lub sijhawm ntev dua. Granite kuj tiv taus feem ntau cov tshuaj lom neeg thiab cov kua qaub, uas ua kom ntseeg tau tias nws tseem tsis muaj xeb txawm tias siv ntev.
Thaum kawg, cov pob zeb granite spindles thiab cov rooj ua haujlwm yooj yim los ntxuav thiab tswj. Granite muaj qhov chaw du uas tsis yooj yim khaws cov av lossis cov khib nyiab. Qhov no ua kom lub tshuab ntsuas tseem huv, uas yog qhov tseem ceeb rau kev ntsuas kom raug thiab txhim khu kev qha. Ntxiv mus, kev saib xyuas cov khoom granite yog tsawg heev, uas ua rau lawv pheej yig thiab siv tau.
Xaus lus, kev siv cov granite spindles thiab worktables hauv cov tshuab ntsuas peb-seem yog qhov tseem ceeb rau kev ua kom ruaj khov thiab kev tswj kev co hauv qab kev txav mus los ceev. Kev siv granite muab cov qauv ruaj khov, nruj, thiab hnav-resistant uas ua rau qhov tseeb thiab qhov tseeb ntawm lub tshuab ntsuas. Nws kuj ua kom muaj kev ruaj khov thermal thiab txo qhov kev pheej hmoo ntawm thermal deformation thiab distortion. Ntxiv mus, granite yooj yim los ntxuav, tswj, thiab pheej yig hauv lub sijhawm ntev. Yog li ntawd, kev siv granite spindles thiab worktables yog qhov pom zoo heev rau txhua tus neeg uas tab tom nrhiav kom ua tiav qhov ntsuas tseeb thiab txhim khu kev qha.
